Kakao said Tuesday that most of its services are in almost full operation, after being disrupted due to a fire, with some mail services remaining partially down.

Services of Kakao affiliated units, including KakaoBank, Kakao Map, Kakao T, Kakao Navi, Kakao Page, Kakao Webtoon, Melon and Kakao Games, had been fully normalized around Tuesday morning, according to the company.

KakaoTalk, the most popular mobile messenger in the country of 51 million people, with 43 million monthly active users, is operating normally, but some of its services for backups and shopping are still unavailable.

The company said the recovery process for its internet portal Daum is still underway.

"Functions of Kakao Mail were fully restored as of 9 a.m. and we're now working to repair the mailing service on Daum," a Kakao official said.

Nearly all online services provided by Kakao, ranging from online messenger KakaoTalk to banking service Kakao Bank and traffic app Kakao T, suffered a massive malfunction from Saturday afternoon due to a fire at SK C&C located in Pangyo, just south of Seoul.
